Cross-device targeting is a digital advertising strategy that allows marketers to reach the same person or household across multiple devices, such as smartphones, tablets, laptops, and connected TVs.
Instead of treating each device as a separate user, cross-device targeting uses identity graphs and data signals to recognize when multiple devices likely belong to the same individual or household. This allows advertisers to deliver more consistent messaging and better manage how often ads are shown across screens.
How It Works
Cross-device targeting uses technologies such as deterministic and probabilistic matching:
- Deterministic matching: Links devices using known identifiers such as logins or authenticated accounts.
- Probabilistic matching: Uses machine learning and signals like IP address, device location, and behavioral patterns to estimate which devices belong to the same user.
Why It Matters
Consumers often switch between devices throughout the day.
- Reach users wherever they are browsing or streaming
- Deliver consistent messaging across screens
- Improve ad frequency control
- Increase campaign efficiency and audience reach
Example
A consumer might:
- See an ad on their smartphone in the morning
- Later see a related ad on their laptop at work
- Then encounter the brand again while streaming content on their connected TV at night
Cross-device targeting allows advertisers to coordinate messaging across all those devices, increasing the likelihood of engagement and conversion.
Household Targeting
Some cross-device solutions also include household-level targeting, which connects devices used within the same home. This is especially valuable for Connected TV advertising, where multiple viewers may share the same screen.
In short, cross-device targeting shifts advertising from device-based marketing to audience-based marketing, helping brands reach real people across their digital ecosystem.
